Sintering material layer thickness control method and apparatus of the sintering machine

摘要

PROBLEM TO BE SOLVED: To provide a method for controlling the layer thickness of sintering a raw material in a sintering machine, capable of properly controlling the layer thickness of the sintering raw material at the inlet side of the sintering machine.;SOLUTION: A first gate opening command value to the split gate is determined based on a gate opening reference value to the split gate which is determined based on the ignition furnace inlet-side layer thickness, a first opening correction value based on a palette conveyance rate and a feeder rotation speed, and a second opening correction value based on the amount of volume decrease of the sintering raw material layer at the start of ignition and suction, which is obtained from the ignition furnace inlet-side layer thickness and the ignition furnace outlet-side layer thickness. A second gate opening command value is determined based on the gate opening reference value and the first opening correction value. When the moving average value of the ignition furnace lower pressure is a predetermined value or less, the split gate is controlled with the first gate opening command value, and when the moving average value exceeds the predetermined value, the split gate is controlled with the second gate opening command value.;COPYRIGHT: (C)2012,JPO&INPIT
